Brainly y=-1/3x+5 graph
Wewaii [24]

Answer:

The answer will be listed below.

Step-by-step explanation:

To graph the equation, first mark down your y-intercept which would be 5. Look at the y-axis and put a dot on 5. Now you must graph the slope of the line. To graph the slope, you would use rise/run (1/3). You would start on 5 and go up one and to the right three times. Keep repeating the process until you run out. Now draw the line through the dots and you did it!
